NEW YORK (AP) — Stock futures are following overseas markets sharply lower on uncertainty about the role of Asian and European governments in global economic recovery efforts.

Dow Jones industrial futures are down 112 points to 15,116. S&P futures have given up 14.2 points to 1,627.80. Nasdaq futures are down 25.25 points to 2,961.75.

The recovery well underway at home, U.S. markets increasingly look abroad for threats that could derail it, or at least slow it down.

The Bank of Japan closed a two-day policy meeting Tuesday with a more positive outlook, but apparently will not become involved in easing the volatile government bond market, even as the public debt soars.

And a central bank program that helped cool the European debt crisis is facing a legal challenge Tuesday in Germany’s highest court.
